Abstract:
Objective To measure the effect of prostaglandin E1 (PGE1) lipid microsphere on cardiac haemodynamics and oxygen metabolism during the perioperative period in the infants with ventricular septal defect(VSD)and severe pulmonary artery hypertension (PAH).Methods Forty infants [(7.1 ± 3.3) years old] with VSD and severe PAH who underwent surgery under cardiopulmonary bypass were involved in the study.They were divided into 2 groups averagely:control group (20 cases) and experimental group (20 cases).All the patients were continuously intravenous pumping of nitroglycerin or PGE1 during the perioperative period.The effect of PGE1 on cardiac haemodynamics and oxygen metabolism between the 2 groups were measured during 72 hours postoperatively.Results The statistical analysis demonstrated that the values trend of mean arterial blood pressure (mABP),mean pulmonary arterial pressure (mPAP),mPAP/mABP,pulmonary vascular resistance index (PVRI),left ventricular stroke work index (LVSWI) were affected during 72 h postoperative period (P ＜0.05).The mABP at 48 h,LVSWI at 48 h,72 h in experimental group were significantly higher than those in control group (all P ＜0.05).The mPAP at 8 h,48 h,PVRI at 72 h and pulmonary arterial wedge pressure (PAWP)at 12-48 h in experimental group were significantly lower than that in control group (all P ＜ 0.05).Compared to postoperative period,mABP at 12 h,72 h,mPAP at 4-12 h,48 h were increased significantly in control group (P ＜ 0.05) ; mABP and LVSWI at 8-72 h,right ventricular stroke work index at 48 h,72 h and cardiac index at 72 h were significantly increased (P ＜0.05),while PVRI and PAWP at 72 h,mPAP/mABP at 24-72 h were significantly decreased in experimental group (P ＜ 0.05).There were no significant differences in the values of oxygen metabolism between both groups (P ＞0.05).Conclusions LipoPGE1 can significantly decrease the pulmonary arterial pressure,which can enhance cardiac function and decrease the duration of intubation after surgery.
